Overview

The IFS VT/VR7800-2DRDT video transmitter/data transceiver and video receiver/data transceiver series utilizes state-of-the-art 8-bit digital encoding and decoding for high-quality video transmission that exceeds the requirements of EIA RS-250C for Medium-Haul Video Transmission. These environmentally hardened units provide transmission of eight independent video channels and two bi-directional data channels over one optical ﬁber and are ideal for use in unconditioned roadside or out-of-plant installations. Completely transparent to and universally compatible with any NTSC, PAL, or SECAM CCTV camera system, all standard pan-tilt-zoom control signals including RS-232, RS-422, or 2- or 4-wire RS-485 with Tristate. Plug-and-play design ensures ease of installation and no electrical or optical adjustments are ever required. LED indicators are provided for rapidly ascertaining equipment operating status, and these units are available in either stand-alone or rack-mount conﬁgurations.

Application Examples

• High Performance CCTV with PTZ Control

• High Performance CCTV with Access Control

8-Channel Digitally

VT/VR7800-2DRDT Series

Standard Features

• 8-bit digitally encoded video transmission transmits 8 real-time color video signals and 2 bi-directional data signals on one single-mode optical ﬁber

• Supports RS-232, RS-422, and 2- or 4-wire RS-485 with tri-state data interfaces

• LED status indicators provide rapid indication of critical operating parameters

• Exceeds all requirements for RS-250C medium-haul transmission: extremely high video performance

• Exceptionally low video distortion with zero performance variation vs. optical path loss

• Ideally suited to networks requiring multiple physical layers where video degradation may be a problem

• Directly compatible with all NTSC, PAL, or SECAM CCTV camera systems

• Tested and certiﬁed by an independent testing laboratory for full compliance with the environmental requirements (ambient operating temperature, mechanical shock, vibration, humidity with condensation, high-line/low-line voltage conditions and transient voltage protection) of NEMA TS-1/TS-2 and the caltrans speciﬁcation for traﬃc signal control equipment.

• Robust design ensures extremely high reliability in unconditioned out-of-plant environments

• Solid-state current limiters on all power lines provide unconditional equipment protection

• Comprehensive lifetime warranty
